heard the low murmur, as of far-distant, but rapidly approaching, tornado, and the moan would swell unaccountably, even while every pencil was flying, every eye fixed upon the slate. This thing went along for two or three days with no more serious mishap than that twice, without an apparent exciting cause, while Meeker would be elaborately explaining some alleged knotty point to Joy or Lawton, the half-completed stack would edge slowly off the slippery table and topple with prodigious crash and clatter to the floor. Then Meeker bethought himself of a stopper to these seismic developments, and directed that henceforth, instead of being deposited at the corner, the slates should be laid directly in front of him on the middle of the desk. This was most decorously done as much as twice, and then an extraordinary thing occurred. It had occasionally happened that two or even three of the boys would finish their work at the same moment, and in their eagerness to get their slates foremost on the stack a race, a rush, a collision, had resulted. Then these became surprisingly frequent, as many as four boys finishing together and coming like quarter horses to the goal, but the day that Meeker hit on the expedient of piling the slates up directly in front of him, and at the third essay, there was witnessed the most astonishing thing of all. Snipe was always a leader in mathematics, as he was in mischief, and he, Carey, Satterlee, and Joy were sure to be of the first four, but now, for a wonder, four, even five, minutes passed and not a slate was in. "Come, come, gentlemen," said Meeker, "there's nothing remarkable in this example. I obtained the result with the utmost ease in three minutes." And still the heads bent lower over the slates and the pencils whizzed more furiously. Five minutes went by. "Most astonishing!" said Meeker, and began going over his own work to see if there could be any mistake, and no sooner was he seen to be absorbed thereat than quick glances shot up and down the long bench-line and slates were deftly passed from hand to hand. The laggards got those of the quicker. The experts swiftly straightened out the errors of the slow, and some mysterious message went down from hand to hand in Snipe's well-known chirography, and then, just as Meeker would have raised his head to glance at the time and warn them there was but half a minute more, as one boy up rose the twenty-seven and charged upon him with uplifted slates. Batter, clatter, rattle, bang! they came crashing down upon the desk, while in one mighty, struggling upheaval the class surged about him and that unstable table. "But those behind cried 'Forward!' And those before cried 'Back!'"
